Scent dispensing apparatus

ABSTRACT

The invention provides for an apparatus for dispensing scent.

TECHNICAL FIELD

This invention relates to an apparatus, and more particularly to an apparatus for scent delivery.

BACKGROUND

A variety of scents are used frequently by, for example, hunters and gardeners to attract and/or repel animals. Scents generally include attractant scents, repellant scents, and covering scents. Attractant scents are used to attract specific animals (e.g., male deer); repellant scents are used to keep animals away (e.g., from a garden); and covering scents typically are used to mask human odor (e.g., while hunting or photographing animals). For example, animals use pheromones and other hormones to communicate with one another. Thus, one or more hormones can be used as either an attractant scent or a repellant scent depending on the hormone(s).

DETAILED DESCRIPTION

The apparatus disclosed herein for dispensing scent can be used, for example, by hunters or wildlife photographers to “pattern” an animal and/or to cover their own scent, or by a gardener to keep animals or birds away from plants or flowers. A number of devices for delivering a scent are available, but none that have the features and flexibility of the apparatus disclosed herein. FIG. 1 is a schematic showing one embodiment of a scent dispenser 1. With reference to FIG. 1, the scent dispenser 1 has a variable timer a scent dispenser 20, and a container 30 for holding the scent. The scent dispenser 1 shown in FIG. 1 is powered by a battery pack 40 and has an on-off switch 50.

A variable timer 10 includes, for example, a programmable timer. A variable timer 10 can be programmable for the particular time (e.g., of day or night) of delivery, for the interval between deliveries, for the duration of delivery, or for any combination thereof. The variable timer 10 shown in FIG. 1 has a setting for both the interval between scent delivery and the duration of scent dispensing. A variable timer 10 also can be programmable for the condition(s) under which delivery occurs. Such conditions can include, without limitation, motion, temperature, weather, moon phase, ambient lighting, or any combination thereof. A variable timer as described herein provides the user with the utmost flexibility in when and under what conditions a scent is delivered.

The container 30 shown in FIG. 1 is a bag-type container. An apparatus for dispensing scent 1 can be configured to use any type of container 30 that holds a scent (e.g., a flowable scent). A scent-holding container 30 can be, without limitation, a bag, a vial, a bottle, a bladder, a chamber, or a cartridge. A scent-holding container 30 can be a permanent part of the apparatus or can be removable. A permanently attached container can be refillable via a port (e.g., a fill intake) having, for example, a screw-top or a snap-top. A removable container can be removed and refilled via a port, or replaced with another container. A container can be provided to a user already containing scent, or a user can obtain one or more empty containers and fill them with the desired scent(s).

An apparatus for dispensing scent 1 as described herein also includes a fitting 60 to connect the scent-holding container 30 to a scent dispenser 20 such that the connection can be made without having to open the container 30. For obvious reasons, users do not want to contaminate themselves with scent. A scent container 30 and a scent dispenser 20 can be connected directly to one another via such a fitting 60, or can be connected, for example, via tubing 62 or other means of maintaining fluid communication that has such a fitting 60 at one end. FIG. 1 shows an embodiment in which the scent dispenser 20 possesses one component of a fitting 60 (a piercing member 22) and the scent-holding container 30 possess another component of a fitting 60 (a pierceable member 32). Fittings suitable for use in an apparatus as disclosed herein include, for example, luer lock fittings, press-fit fittings, snap-fit fittings, screw-on fittings, or piercing-type fittings.

The tubing can be connected to the bag via a luer lock fitting 60 and to the scent chamber via a luer lock or a press-fit fitting 60. As shown in FIG. 7, the connection can be at any position along the length of the tubing.

When a scent dispensing apparatus 1 is used in a region that experiences cold weather, it is desirable that the scent S not freeze. Therefore, an apparatus 1 can include a heating element or a reservoir for holding a heating element. A heating element or a reservoir for holding a heating element can be proximal to the scent dispenser 20 and/or the container 30 containing the scent S. A heating element can be an electrical heating element or a chemical heating element, and can be removable. Electrical heating elements can be powered, for example, by a power supply 40 as described above, while chemical heating elements are known in the art. See, for example, U.S. Pat. Nos. 3,998,749; 4,265,216; 4,725,225; and 4,862,519.

Scents S suitable for use in a scent dispensing apparatus 1 can be, for example, an attractant scent, a repellant scent, or a covering scent. It would be understood by those of skill in the art that the three types of scents described here are not comprehensive and also that members are not exclusive to each type of scent. Representative examples of attractant scents include urine, estrus, glandular secretions, hormones, pheromones, apple, acorn, berry, honey, or bacon; representative examples of repellant scents include insect repellant, animal repellant, urine, pepper spray, or any type of noxious and/or irritating chemical or compound; and representative examples of a covering scent include soap, earth, pine, cedar, corn, acorn, apply, berry, persimmon, vanilla, anise, animal urine, or animal musk.

A scent S such as any of those described above can be formulated, without limitation, as a flowable solid, a flowable powder, a flowable gel, or a flowable liquid. The particular formulation will be dependent upon the container 30 and the scent dispenser 20 utilized in a scent dispensing apparatus 1, as well as the characteristics of the particular scent S and the area or region to which the scent is being dispensed or applied.

An apparatus for dispensing scent 1 can be configured to dispense multiple scents. For example, an apparatus 1 can include two containers 30 a, 30 b and two scent dispensers 20 a, 20 b, or two containers 30 a, 30 b and a single scent dispenser 20 having two orifices 28 a, 28 b. In such dual-scent embodiments, the apparatus 1 (e.g., the variable timer 10) can be programmed to deliver one scent at a particular time via, for example, a nozzle 28 a and the other scent at a different time via, for example, a wick 28 b.

An apparatus for dispensing scent 1 can be used in methods of attracting one or more animals (e.g., a game animal), methods of repelling one or more animals (e.g., a nuisance animal), or methods of covering a scent (e.g., one's own scent). To do so, an apparatus 1 can be placed in any number of positions by a user. To allow for flexibility in positioning the apparatus 1, an apparatus 1 can include one or more straps, buckles, D-rings, or any other types of mechanisms or means that allow an apparatus 1 to be attached or secured to another object. In some instances, a user may hang or suspend the apparatus 1 from a tree or tree branch such that the scent drips down into the ground or runs down the tree. In other instances, a user may securely attach the apparatus 1 to a tree or a post such that a mist or spray is emitted in a particular direction and covers a particular area.
